Abstract
The invention discloses a full-insulated full-enclosed compact type outdoor vacuum circuit breaker and relates to the fields of protection and control technologies in the distribution systems of industrial and mining enterprises and converting stations. The outdoor vacuum circuit breaker comprises a pole of a connection; the upper end of the pole is hermetically connected with an upper wire seat; a feeding cable clamp is arranged in the upper wire seat; one side of the pole is hermetically connected with a lower wire seat; a discharging cable clamp is arranged inside the lower wire seat; a vacuum arc-extinguishing chamber is arranged in the inner chamber of the pole; and the upper of the vacuum arc-extinguishing chamber is connected with the inner end of the feeding wire cable clamp. According to the full-insulated full-enclosed compact type outdoor vacuum circuit breaker, two joints become to be one joint, the upper discharging seat and the lower discharging seat are all sealed inside the pole, and an external connection cable can be directly inserted inside the pole, so that the exterior of the pole does not have an exposed primary conductive part, and the insulation property is greatly improved.
Description
Technical field
The present invention relates to protection and control technology field in transformer station and the industrial and mining enterprises' distribution system.
Background technology
Existing 10kV outdoor AC high-voltage vacuum circuit-breaker will be used for power distribution network and cut-off, closes the load current, overload current and the short circuit current that close electric power system.Principal organ's characteristics:
1, existing outdoor vacuum circuit breaker main body structure form is a casing three-phase column support type, mainly is made up of six parts such as conduction arc quenching system, insulation system, drive system, operating mechanism, housings.Because mechanism's parts are various, failure rate is higher;
2, pole is divided into two sections, and mid portion is gapped, and pole inside makes moist easily;
3, vacuum interrupter is placed in the pole, and vacuum interrupter and pole inwall have the air gap, are easy to generate flashover;
4, according to user's request 200/5～600/5 current transformer can be installed, following outlet and pole link position are gapped, are placed on outdoor rainwater for a long time and infiltrate wherein decreasing insulating.
Summary of the invention
The object of the invention is to design a kind of solid full outdoor AC high-voltage vacuum circuit-breaker that seals of all insulation that can improve moisture effect.
The present invention includes the pole of disjunctor; The seat of reaching the standard grade is tightly connected in the upper end of said pole; In the seat of reaching the standard grade, arrange the inlet wire cable clip, connect the seat that rolls off the production line, layout outlet cable clip in the seat that rolls off the production line in a side seal of pole; At said pole inner chamber vacuum interrupter is set, the upper end of said vacuum interrupter links to each other with the inner of said inlet wire cable clip.
Ruuning situation from ZW32; Outdoor products subject matter is exactly rainproof protection against the tide, and original pole form is that two joint butt joints form up and down, and the present invention not only becomes a joint with two joints; And the outlet seat all is enclosed in pole inside admittedly up and down; External cable can directly be inserted into the pole the inside, does not have exposed primary conductive part thereby reach the pole outside, and insulation property improve greatly.
The present invention also can directly be poured into vacuum interrupter in the pole, can further improve insulation property, truly reaches all insulation and consolidates seal structure entirely.
The present invention is because above design; Can make original three the single-phase poles of product change the whole pole of three-phase integratedization into; Thereby spaced apart reduces, and the volume of bottom mechanism case also can further dwindle, and insulation property improve; Have characteristics such as parts are few, power consumption is low, simple to operate, further prolonged the service life of outdoor circuit breaker.
Description of drawings
Fig. 1 is a kind of structural representation of invention.
Fig. 2 is that the A-A of Fig. 1 is to cut-away view.
Embodiment
Like Fig. 1, shown in 2; The present invention includes the pole 1 of the disjunctor of three-phase integrated setting, the seat 2 of reaching the standard grade that is tightly connected in the upper end of pole 1 is arranged inlet wire cable clip 3 in the seat 2 of reaching the standard grade; Side seal at pole 1 connects the seat 4 that rolls off the production line, and in the seat 4 that rolls off the production line, arranges outlet cable clip 5.
At pole 1 inner chamber vacuum interrupter 6 is set, the upper end of vacuum interrupter 6 links to each other with the inner (being the lower end) of inlet wire cable clip 3.
7,8 are respectively into and out of the line cable among the figure.
Claims (1)
1. all insulation is sealed the compact outdoor vacuum circuit breaker entirely admittedly; It is characterized in that comprising the pole of disjunctor, the seat of reaching the standard grade that is tightly connected in the upper end of said pole is arranged the inlet wire cable clip in the seat of reaching the standard grade; Side seal at pole connects the seat that rolls off the production line; In the seat that rolls off the production line, arrange the outlet cable clip, at said pole inner chamber vacuum interrupter is set, the upper end of said vacuum interrupter links to each other with the inner of said inlet wire cable clip.
